Determinants of continuance intention to use the smartphone banking services: An extension to the expectation-confirmation model

Purpose – Existing research in the electronic banking area has not deeply investigated the determinants of continuance intention to use smartphone banking services. The purpose of this paper is to attempt to do so by investigating continuance use intention at the post-consumption phase. Design/methodology/approach – It developed and validated an extended framework based on the expectation-confirmation model (ECM). A total of 301 smartphone users who subscribed to online banking services participated in the study. Findings – The results revealed that users’ confirmation after the initial use of smartphone banking services has significant impact on perceived security, perceived usefulness, trust, and user satisfaction. Perceived security significantly influences trust while perceived usefulness significantly influences trust, user satisfaction, and continuance use intention. Both user satisfaction and self-efficacy also significantly influence continuance use intention. Trust exerts significant impact on us...

The role of perceived information practices on consumers’ intention to authorise secondary use of personal data

ABSTRACT We are living in an era where data lead to opportunities, especially customer data. According to privacy laws, however, without customers’ authorisation, organisations face many limitations in using identifiable information for secondary purposes. Consequently, organisations are missing out on many potential business opportunities to capitalise on customer data. Privacy concerns have become the biggest roadblock to gain customer consent because of the potential risks associated with the use of personal information. This situation underscores the importance of devising effective information practices and strategies in dealing with the use of customer data. Privacy literature suggests that information practices may influence individuals’ intentions to participate in situations requiring the collection and use of personal data. Yet, existing research has not systematically analysed the role of these strategies in influencing intention. Also, previous studies focus primarily on the disclosure of personal data. Issues surrounding ‘authorisation of personal data for secondary use’ remain unexplored. The purpose of our study is to examine the role of information practices on intention to authorise secondary use of personal data. The results show that privacy concerns and trusting beliefs significantly affect individual perceptions of information practices. Perception of information practices in turn exerts significant effect on intention to authorise secondary use of personal data. Both theoretical and managerial implications of the results are discussed.

Knowledge sharing behavior among community members in professional research information centers

South Korea is a world leader in human capital and research investment. However, compared to other countries with similar levels of resource input, Korea has relatively weaker output performance. This is a concern for the Korean government and the funding agencies that invest heavily in R&D activities. Since knowledge sharing among members influences the output performance within an R&D sector, this paper investigates the factors that affect the knowledge sharing intention and behavior among members of a national R&D center in Korea. A total of 286 members in the Biology Research Information Center participated in a survey. The results show that intrinsic and extrinsic motivations significantly influence the members’ intention to share knowledge. Cognitive and relational capital also exert significant effects on the members’ knowledge sharing intention. Structural capital, however, does not have any significant effect on intention. The members’ intention to share knowledge links significantly to their actual knowledge sharing behavior.

Privacy concerns and benefits in SaaS adoption by individual users A trade-off approach

Software-as-a-Service, a new model of accessing software, presents individual users with tremendous opportunities to work and live conveniently and efficiently. Existing research has put much focus on understanding SaaS potential and risks for organizations and not much effort has been invested in understanding individual users, despite their market significance. This study aims at closing this gap by analyzing the cognitive mechanism through which individual users trade off privacy against the benefits that SaaS offers and identify salient benefits that trigger such trade-off. Based on the Theory of Reasoned Action, the Privacy-Trust-Intention model and cost-benefit theories, we developed a research framework that capture the trade-off between benefits and privacy and further analyzed data collected from an online survey of SaaS users in Korea with 290 respondents. Our findings indicate that individual users’ intention to use SaaS is negatively affected by privacy concerns and positively affected by overall perceived benefits in a relationship that is mediated by trust towards SaaS providers. Surprisingly, no direct, significant effect of privacy concerns on intention to use SaaS was found, whereas overall perceived benefits were found to have a direct effect on users’ intention to adopt SaaS. We found convenience to be the most salient benefit that users expect from adopting SaaS. Our study contributes to existing research by developing and empirically verifying a benefits-versus-privacy framework in a rather neglected segment of SaaS consumers in previous research. The findings also guide SaaS providers in mitigating privacy concerns; while efforts to minimize privacy will enhance users’ trust, it is of paramount importance to maximize salient benefits such as convenience that outweigh privacy concerns during users’ decision making to adopt SaaS.

A Comparison of the Digital Divide Across Three Countries with Different Development Indices

The digital divide between countries is a critical phenomenon that places developing countries in a disadvantaged position economically, politically, and socially. While the phenomenon has drawn the attention of many, a theoretical account using empirical test of primary data is lacking. Building on a three-level digital divide framework, this study tested the effect of country development index on three levels of the digital divide. Survey data from university students in Cambodia, Iran, and South Korea show that country development index has a significant effect on all three levels of the digital divide. While the countries differ on the hedonic values of IT use, there is no significant difference in the utilitarian values of IT use. Korea, being a developed country also differs significantly from Cambodia and Iran in the digital access divide, digital capability divide, and digital usage divide. The results have important implications for companies as well as government policy-making and intervention programs.

A Study on the Use Contexts of Personal Computing Devices Using a Diary Study Method

In this study, the use contexts of personal computing devices (desktops, laptops, net books, tablets, and smartphones) are investigated in order to verify the existence of use context differences between different devices. Based on previous research, categorizations for the use context and sub-use context factors are proposed. A diary study method with a large number of samples is used to extract and define the use contexts. Also, a cross-tabulation analysis is used in the hypothesis testing. The results of this study demonstrate that the use context differs for each device. Therefore, it appears that the use contexts may have an effect on user behavior regarding different devices and services. The use context can be applied and extended to future research in order to measure the use context and to examine the effect of the use context on user behavior with the devices and services. This research provides a significant contribution as the first empirical study to verify the use context of personal computing devices and it is a foundational study for the development of measurements for use contexts.
